/**
* index.ts - Main server orchestration
*
* This file serves as the entry point for the Google Maps MCP server.
* It initializes the MCP server, registers all available tools, and
* dispatches incoming tool call requests to their respective handlers.
*
* Dependencies:
* - @modelcontextprotocol/sdk/server/index.js (for Server)
* - @modelcontextprotocol/sdk/server/stdio.js (for StdioServerTransport)
* - @modelcontextprotocol/sdk/types.js (for CallToolRequestSchema, ListToolsRequestSchema)
* - ./registry/tool-registry.js (for ALL_TOOLS)
* - All handler files (e.g., geocoding.ts, places.ts, etc.)
* - ./utils/error-handling.js (for createErrorResponse)
